Which statement is supported by the evidence to support the claim about the amount of force needed to accelerate an object?



A.
The basketball would need more force than the bowling ball, because as the mass decreases, the amount of force needed increases.

B.
The bowling ball would need less force than the basketball, because as the mass increases, the amount of force needed decreases.

C.
The rock would need more force than the basketball, because as the mass increases, the amount of force needed increases.

D.
The basketball would need more force than the rock, because as the mass decreases, the amount of force needed increases.

Answer 1

C

Force needed to produce the same acceleration increases with mass (F = ma). The rock has more mass than the basketball, so the rock would need more force than the basketball.
